ABSTRACT

Trichoblastoma is characterized as a benign cutaneous neoplasm that originates in the trichoblastic epithelium of the hair bulb. The present report describes the case of a 4-year-old cross breed neutered male cat that had a history of a slow, freely movable, ulcerated, slow growing, solitary cutaneous nodule located on the left scapular region. Histopathological evaluation showed neoplastic cells arranged in cohesive nests or palisades with eosinophilic and scant cytoplasm. Based on the microscopic findings, a diagnosis of trabecular trichoblastoma was made. The treatment of choice consisted of total surgical excision of the mass with safe surgical margins. Tumor recurrence was not observed.(AU)


O Tricoblastoma se caracteriza como uma neoplasia benigna cutânea que tem origem no epitélio tricoblástico do bulbo piloso. O presente relato descreve o caso de felino macho, sem raça definida (SRD), com histórico de nódulo solitário de crescimento lento, não aderido e ulcerado, localizado na região escapular esquerda. A histopatologia evidenciou células neoplásicas organizadas em ninhos coesos, em paliçadas com citoplasma eosinofílico e escasso, os achados foram compatíveis com a descrição de tricoblastoma trabecular. O tratamento de eleição consistiu na exérese cirúrgica total da massa com ampla margem de segurança e recidivas não foram observadas.(AU)
